Designing Value Classes for Modern C++
summary
Covers principles for designing value classes in modern C++, discussing how to implement safe, efficient value semantics using C++11/14 features such as move semantics, constexpr, and noexcept. Explains trade-offs in copy vs. move, resource management, and API design to make value types predictable and performant.
